The study identifies a regulatory mechanism in the potato resistance protein Rpi-vnt1.1 where surface immune signaling triggers alternative splicing to remove an inhibitory N-terminal prodomain. This process prevents autoimmunity while allowing the NLR receptor to be activated by the Phytophthora infestans effector AVRvnt1, facilitating resistosome assembly and immune response.
This study evaluates the physicochemical and sensory properties of starch-based gel confectionery using different starch sources, including potato starch. The research highlights that potato starch formulations produced the softest gels and exhibited delayed moisture release compared to corn and mung bean starches.
This study confirms polyandry in the potato cyst nematode Globodera pallida and investigates how this reproductive behavior changes during adaptation to resistant potato cultivars carrying the GpaV gene. The research demonstrates that multiple paternity is highly prevalent in G. pallida populations and remains stable even when facing masculinizing plant resistance, providing insights for nematode control strategies.
This study develops biodegradable active films using potato starch and potato peel extract to enhance the preservation of fresh-cut potatoes. The research demonstrates that these potato-derived films possess significant antioxidant and antimicrobial properties, effectively reducing browning and delaying spoilage during storage.
This study investigates how replacing potato tissue with dry starchy ingredients like granulates and flakes, along with the addition of HPMC, affects the texture and oil absorption of deep-fried potato mashes. The research provides insights into tailoring the physical properties and nutritional profile of potato-derived food products.
This study identifies and characterizes over 11,000 long non-coding RNAs (lncRNAs) involved in the various stages of potato tuberization. By integrating transcriptomic and phytohormonal data, the research reveals complex regulatory networks where lncRNAs influence key tuberization genes and hormonal signaling, offering new insights into the functional genomics of potato development.
This study investigates how different oral processing behaviors, such as chewing rate and tongue-palate compression, affect the starch digestibility and bolus properties of mashed potatoes. The findings indicate that modulating chewing behavior can significantly influence starch hydrolysis rates, providing insights into the nutritional impact and glycemic control of potato-derived food products.
Researchers used Cas12a-mediated gene editing to target the eIF4E1 gene in potatoes to develop resistance against Potato Virus Y (PVY). The study identified a specific mutation that confers dominant-negative resistance, offering a more effective strategy for engineering potyvirus resistance than traditional gene knockout approaches.
This study investigates the use of low-molecular-weight protectants, particularly sorbitol, to reduce cellular damage in potato slices during the freeze-drying and rehydration process. The findings show that these treatments improve the rehydration ratio, moisture distribution, and microstructural integrity of the potato tissue, resulting in better textural properties.
This study evaluates the effectiveness of various summer and fall cover crops, such as sunn hemp and caliente mustard, in managing sting and stubby-root nematodes in Florida potato production. Results indicate that sunn hemp can suppress sting nematode populations and improve potato yields, whereas certain fall cover crops like arugula and caliente mustard may negatively impact marketable yield.
